Threaded Ring Recessed Downlight for Quick Lens Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional downlight fixtures require the entire assembly to be removed for adjusting light output and distribution, which is time-consuming and cumbersome.
Innovation Solution
A recessed downlight fixture with a threaded ring that supports and retains a lens and reflector, allowing for quick replacement without removing the entire fixture, enabling customization of light output and distribution by unscrewing the ring to swap out the lens and reflector components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire fixture assembly is removed to replace lens and reflector components, then the light output and distribution can be customized, but the time and effort required for maintenance and adjustment increases significantly
Solution Approach 1:
The fixture is divided into separable components: a fixed base assembly containing the light source and a removable ring assembly containing the lens and reflector. This segmentation allows the lens and reflector to be replaced independently without removing the entire fixture, resolving the contradiction between adaptability and time loss.
Solution Approach 2:
The lens and reflector are extracted from the fixed base assembly and placed in a removable ring structure. This extraction enables these components to be easily removed and replaced by simply detaching the ring, rather than removing the entire fixture, thus reducing replacement time while maintaining customization capability.
2Adaptability or versatility
If the entire fixture assembly is removed to adjust light distribution, then component replacement is possible, but the complexity of the adjustment process increases
Solution Approach 1:
By segmenting the fixture into a fixed base and a removable ring assembly, the adjustment process is simplified to merely detaching and reattaching the ring, making light distribution adjustment easy while maintaining adaptability.
Solution Approach 2:
The ring assembly is designed with dynamic removability, allowing users to easily attach and detach it for adjustments. This dynamic design makes the adjustment process simple and intuitive while preserving the ability to customize light distribution.
3Stability of the object's composition
If the light source is secured permanently in the fixture, then the structural integrity is maintained, but the ability to modify the entire assembly is reduced
Solution Approach 1:
The fixture is segmented into a permanently fixed base assembly (maintaining structural integrity) and a removable ring assembly (enabling component replaceability). This segmentation resolves the contradiction by allowing different parts to have different levels of permanence.
Solution Approach 2:
Different parts of the fixture have different qualities: the base assembly has permanent fixation for stability, while the ring assembly has removable fixation for adaptability. This local differentiation of fixation quality resolves the contradiction between stability and replaceability.

AI summary
A light fixture that allows for customization and easy adjustability of various properties of the distributed light. The light fixture includes a threaded ring that engages with threads of a heat sink to support and retain a lens and/or reflector within the fixture. Because the threaded ring retains the lens and reflector within the fixture, unscrewing the threaded ring allows the lens and/or the reflector to be replaced without having to remove the entire fixture.
